Use of barrier membranes to direct bone regeneration was first described in the context of orthopaedic research 1959. [2] The theoretical principles basic to guided tissue regeneration were developed by Melcher in 1976, who outlined the necessity of excluding unwanted cell lines from healing sites to allow growth of desired tissues.

In dentistry, the subepithelial connective tissue graft (SECT graft, and sometimes referred to simply as a connective tissue (CT) graft) is an oral and maxillofacial surgical procedure first described by Alan Edel in 1974. [1]
Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months. [3]
Age, bone type, drug therapy and pre-existing bone pathology are factors that affect healing. The role of bone healing is to produce new bone without a scar as seen in other tissues which would be a structural weakness or deformity. [2] The process of the entire regeneration of the bone can depend on the angle of dislocation or fracture.
Regenerative endodontic procedures suggests that free nerve endings of the root end are guided into the canal by specific chemical signals. Nonetheless, the presence of nerve endings suggests the presence of a vital tissue that is immune-competent due to the intimate association of innervation with blood vessels and the immune system.
This creamy slow-cooker leek soup showcases leeks’ mild onion flavor, enhanced by plenty of fresh and dried herbs and with potatoes adding texture and body.
It is still unclear exactly how EMD participates in the regeneration process. [5] But it has been demonstrated that EMD serves to promote periodontal ligament fibroblast proliferation and growth and inhibit epithelial cell proliferation and growth; [3] this is a key feature in EMD-promoted periodontal tissue regeneration, because the faster-growing epithelium will ordinarily compete very ...
